Abstract:
Multi-valued decision diagrams (MDD) have recently been proposed to address the reliability analysis of complex multi-state systems. In this talk I will present our recent development on applying the MDD-based approach to the reliability analysis of phased-mission systems (PMS), which are systems involving multiple, consecutive and non-overlapping phases of operation. Both single-mode and multi-mode failures are considered. Furthermore, the MDD-based solutions are presented for analyzing systems subject to dependent common-cause failures. As compared with the traditional methods, the MDD-based solutions require less computer storage and are more computationally efficient. Several case studies will be presented.
